A July 6, 2026 Bloomberg feature reports women now drive prenuptial agreement adoption as much as men, per a Harris Poll of 2,148 adults. For California couples, this matters because prenups here are governed by the strict Uniform Premarital Agreement Act — and enforceability hinges on procedures most people skip.

Why this matters legally
A prenuptial agreement is now mainstream financial planning, not a signal of distrust. Bloomberg's reporting reflects a genuine legal shift: couples marrying later bring more pre-existing assets — retirement accounts, home equity, business interests, and student debt — into marriage, and they want those assets addressed before commingling begins.
The legal significance is concrete. In community property states like California, everything earned during marriage is presumptively owned 50/50 under Cal. Fam. Code § 760. A prenup is the only reliable way to alter that default before the wedding. The Harris Poll's finding that women drive adoption tracks the data: the median first-marriage age reached record highs of 30.2 for men and 28.6 for women, and rising female earnings mean more women have separate property worth protecting.
This changes the negotiating dynamic. When both spouses enter marriage with careers and assets, a prenup becomes a mutual document rather than one partner shielding wealth from the other. That mutuality also strengthens enforceability, because courts scrutinize agreements that appear one-sided.
How California law handles this
California enforces prenuptial agreements under the Uniform Premarital Agreement Act, codified at Cal. Fam. Code § 1600 and following sections — but the enforcement bar is high. An agreement can be thrown out if it fails the state's procedural safeguards.
Three requirements matter most. First, under Cal. Fam. Code § 1615, a prenup is unenforceable if it was not executed voluntarily or was unconscionable when signed. Second, California imposes a mandatory seven-day rule: the party against whom enforcement is sought must have had the agreement for at least seven calendar days before signing, giving time to review it with counsel. Third, if a spouse waives the right to independent legal counsel, that waiver must be in a separate signed document.
Spousal support waivers face extra scrutiny. Under California law, a provision waiving spousal support is unenforceable if the party challenging it was not represented by independent counsel when signing, or if the waiver is unconscionable at the time of enforcement. This is why the reframing Bloomberg describes — treating prenups as ordinary planning — actually helps: agreements negotiated calmly, with both parties represented, survive challenge far better than rushed, lopsided ones.
Full financial disclosure is also essential. A prenup can be voided if either party failed to provide a fair and reasonable disclosure of property and debts, and the challenging party did not waive disclosure in writing. Hiding a business interest or retirement account is a common way agreements collapse years later.
Practical takeaways
-
Start early. California's seven-day review rule under Cal. Fam. Code § 1615 means you should finalize a prenup weeks before the wedding, not days. Sign at least seven calendar days after receiving the final version.
-
Each party needs independent counsel. One lawyer cannot represent both fiancés. If a spouse waives counsel, that waiver requires its own signed document — and waiving is rarely wise where a spousal support provision is involved.
-
Disclose everything in writing. List every account, property, business interest, and debt — including student loans. Incomplete disclosure is a leading reason California courts void agreements.
-
Address separate property specifically. Identify pre-marriage retirement balances, home equity, and business ownership so they stay separate under Cal. Fam. Code § 770 rather than becoming community property through commingling.
-
Consider a postnuptial agreement if you are already married. Couples who missed the prenup window can address the same concerns after the wedding; learn how postnuptial agreements differ in disclosure and fiduciary duties.
-
Revisit the document after major life events. A prenup drafted at 28 may need review after a business launch, an inheritance, or the birth of children.
The Bloomberg data confirms what California family lawyers have seen for years: prenuptial agreements are becoming a normal step in financial planning, not a red flag. If you are engaged and weighing one, the smartest move is to understand the mechanics before you draft anything.
